To all whom t may concern.

Be it known that I, RExDE ORE MGDILL, a citizen of the United States, and a resident of Cienfuegos, in the Proviice of Santa Clara, Cuba, have invented a new anduse- ,ful Machine for Applying a Liquid Coating or Preservative to the Skin of Fruit.

The object of my invention isto provide novel apparatus for rapidly and evenly applying a suitable water repelling liquid coating or preservative Vto the surface of the skin of fruit and which is'adapted to handle large quantit-ies of fruit with rapidity. It is. also my object to provide in such a machine novel means for constantly stirring up the mixture forming the liquid coating; and

to provide the novel com ination and arrangement of parts hereinafter disclosed. I attain these and other objects of my invenabsorbent fabric belt, (which may be perforated if desired) engaged b the splkes 4 ,of the rotating roller 2 whic member propels the fabric belt through the liquid coating or preservative in the tank 1.

As shown in Fig. 1, the fruit is fed down a suitable chute 15 and into contact with the endless fabric belt 5 which extends down below the bottom of the exterior of the tank 1 and in proximity to the chute 15 as illustrated in Fig. 1.

lVhat I claim 1. A machine for applying a preservative liquid coating to fruit, consisting of a tank adapted to contain a suitable water repelling liquid coating, an absorbent fabric belt, means for driving the belt, and means for agitating the liquid, coating in the tank, aforesaid belt being suitably arranged to tion by the mechanism illustrated in the acg/ctmtact with and apply the preservative companying drawings, in Which- Figure 1 is a vcrtical'transverse Vsection of my invention;

Fig. 2 is atop plan of same;

Fig. 3 is an enlargeddetail sectional view of the spiked roller; and' Fig. 4 is an enlarged detail view of the agitator 7 l Like numerals indicate like parts in each of the several views.

Referring to the accompanying drawinvs I provide a suitable tank 1 Vhaving suitab e rollers 14- mounted on its longitudinal edffes. I further provide a roller 3 having a multiplicity of spikes 4 having their points protruding through `the surface of therollers. Roller 3 is mounted on a suitable shaft 2, which also carries a pulley or sprocket 1-2 drivenby a suitable belt o'r chain 13 from some suitable source of power.' I further provide a second pulley or sprocket 11 mounted on roller shaft 2,said sprocket driving the belt'or chain 10 'which mturn drives the sprocket or pulley 9 on the agitator shaft Shaft 7 has a pluralit of spaced agitator paddles 8 adapted to eep the ingredients of the liquid coating continuously mixed together while the machine is in operation. I further'provide a broad,

' coating to the fruit.

2. In a machine of the class described, the combination of a tank, rollers mounted on the sides of the tank, an endless fabric belt mounted on the rollers and extending into the tank and around the underside of the tank, means for frictionally engaging the fabric belt and continuously moving same, and means forfeeding fruit intocon-,v

an endless absorbent fabric belt, a spiked roller arranged longitudinally of the tank and engaging the fabric belt to cause same to travel through the solution in the tank, means for agitating the contents of the tank, and means for feeding fruit into contact with the endless fabric belt, whereby quantities of fruit can be rapidly coatedV with the contents ofthe tank.
